[Bug]: AI无法正确使用ManageAsset的Search action，且错误调用该工具会造成Unity卡死 #1177

What happened?

尝试让AI搜索引擎中的某个文件，因为没有提示参数格式，AI极大概率填错参数，search action不会拦截错误，而是直接用空字符串去搜，结果会把整个项目的资源返回，如果项目资源极多，引擎会一直处理GetAssetData

Reproduction steps

1. Open Window > MCP for Unity
2. Click Start Server
3. In Claude Desktop, prompt: "用 manage_asset工具搜索xxx"（xxx为项目的资产名）
4. Observe tool use in Claude Desktop
